What is PromptDeck

From the Chrome Web Store

Manage custom system prompts across ChatGPT, Claude, Gemini & Perplexity. No login. No ads. Works locally. Switch AI system prompts with one click. Built for people who context-switch all day.

ChatGPT, Claude, and Gemini force you into one static system instruction. If you're jumping between code reviews, client emails, brainstorming sessions, and research — you're either retyping prompts or losing your carefully-written instructions.

PromptDeck fixes this.

PRIVACY

Everything runs locally in your browser. No account required. No server. No analytics. No tracking.

Your prompts are stored in Chrome's local storage. They never touch our servers because we don't have servers.

We don't see what you create. We don't know what AI tools you use. We don't collect usage data.

BUILT FOR: -Developers switching between code review, debugging, documentation, and architecture modes. -Writers managing different tone presets for clients, personal projects, and technical content. -Researchers organizing prompts for literature review, data analysis, fact-checking, and synthesis. -Product managers juggling stakeholder communication, technical specs, user research, and roadmap planning. -Anyone using AI tools beyond casual chat. If you have more than 3 different "modes" you use regularly, this will save you time.

ALTERNATIVES & COMPARISONS

ChatGPT custom GPTs: Requires ChatGPT Plus. Doesn't work on Claude or Gemini. Can't export.

Claude Projects: Locked to Claude. No cross-platform support. Heavy for simple prompt switching.

Manual copy-paste: Slow. Error-prone. Requires keeping prompts in a separate doc.

PromptDeck: One tool, all platforms, keyboard-first, fully local.

COMMON QUESTIONS

Does this work with ChatGPT Plus / Claude Pro / Gemini Advanced? Yes. Works with free and paid tiers of all platforms.

Can I sync across devices? Export your prompts as JSON. Import on another device. Manual but works.

Does this inject prompts automatically? No. You select when to inject. Full control, no automation.

Will this work if the AI platforms change their UI? We use fallback selectors. If ChatGPT updates their DOM, we try multiple targeting methods. Updates pushed as needed.
